. BRICK-SURFACING MACHINE.

Application filed March 11, 1922. Serial No. 542,991

T all whom it may concern Be it known that I, JACOB STooKE, Jr.,

a citizen of the United States, and resident of the city bf St. Louisand State of Missouri, have invented certain new and useful Improvementsin Brick-Surfacin Machines,

of which the following is a specification containing a full, clear, andexact description, reference being had to the accompanying l0 drawings,forming a part hereof.

Hy invention relates to improvements in brick surfacing machines, andhas for its object a brick surfacing machine which is provided with anautomatically operated device for scoring or surfacing one side and bothends of a brick simultaneously, so as to produce what is known as a matbrick, and which can be readily attached and detached to any of thepower presses now in use.

In the drawings, Fig. 1 is a front elevation of a brick press with mydeviceattached thereto.

Fig.2 is a side elevation of a brick press with my device in position.

Fig. 3 is a top plan view of a brick press with the ram and end scoringmechanism removed.

Fig. 1 is an enlarged vertical cross section taken through the centralguiding strip and scoring cutters.

Fig. 5 is an enlarged fragmental perspective view, showing one end ofthe end scorin mechanism.

*ig. 6 is a fragmental view of one surface of a brick, showing the samepartially scored by my device.

In the construction of my device I employ a brick press which is ofordinary construction and comprising a frame which is provided withintegrally formed vertical slides or guide ways 7 in which is slidablymounted the ram 8. This ram is operated by means of a lever 9. Securedto the lower end of the ram 8 are plungers 1O which'fit into the moulds11 formed in the table 12 of the press. 12 is a plunger 13 which isprovided with a recess 14. This plunger not only removes the brick afterhaving been pressed but the recess 1 1 becomes filled with clay chargesthe moulds, so that the removing of the finished brick and charging ofthe mould is done in one operation.

Slidably mounted on the table Secured to the front of the press is atable 15 to which smooth guiding strips 16 are.

secured, and a central guiding strip 17 This central guiding strip isprovided with vertical recesses 18, and positioned in these recesses andextending through the strip 17 are the scoring cutters which havecutting edges 19, and a threaded portion 20, so that the same can besecured within the strip 17.

The table 15 is provided with openings 21 which are in alinement withthe vertical recesses 18 and which permitthe material removed from thebricks to pass therethrough,

so as to leave the table clear at all times for l the passage of bricksbetween the strips. Secured to the table 15 are U-shaped frames 22 whichare connected together at their upper edges by bars 23. Mounted on eachof the frames 22 is a bearing 24: through which a shaft 25 passes.Eachpair of legs of the U-shaped frame 22 have extending therethrough arod. or shaft 26. This rod or shaft acting as a guide for the cutterframes 27. Each cutter frame is also U-shaped and is adapted to straddlethe strips 16 and 17 The U-shaped frames are connected together bytie-bars 28 which have extending there through a shaft 29. This shaft isstraddled by the forked end 30 of the operating lever 31. The operatinglever is secured to the shaft 25. Its upper end 32 is curved and isdesigned topass between the rollers 33 and 34; The roller 33 ispivotally secured in a bearing block 35, which block is in turn securedto a bracket 36. This bracket is mounted on the ram 8 and reciprocatestherewith. The roller 34 is mounted in a bearing 37. This bearing issecured to a stud 38 which is slidably mounted in a bracket 39.Interposed between the bearing 37 and bracket 39 is a coil spring 40 forresiliently holding the roller 34 in contact with the end 32 of theoperating lever, The

table 15 is also provided with a plurality of as this part ofthe'mechanism is old and present in all brick presses of a similarnature. This leaves a'brick with vertically extending ribs on both endsand one side. The plunger 13 then moves forward-the ram havingpreviously ascended, and pushes the formed bricks between the strips 16and 17, where the cutting edges 19 form horizontally extending cutsacross the vertical ribs. During this movement the plunger 13 alsocharges the moulds for the next brick. Upon the descent of the plunger,the roller 33 forces the operating lever into the position indicated bydotted lines in Fig. 1. This movement drives the U-shaped frames 27across the ends of the bricks, and the cutters or end scoring blades a2cut horizontal grooves across the ends of the bricks. Upon rising againthe roller operates on the operating lever and forces the ends scorincutters to their original position. The jflunger 13 again comes forward,carrying withit the newly formed bricks. These bricks force the brickspreviously acted on out from between the strips 16 and 1'7 on to theforward portion of the table where they are removed;

By this construction it will be seen that the operation of my device isentirely automatic and mechanical, and the finishing of the brick isdone simultaneous with the pressing of a new brick so that no time islost nor is it necessary to slow down the machine which has been thetrouble where a hand operated device for scoring the bricks is used.

In fact, by the use of my device the speed of the machine is onlylimited by the rate of speed at which the finished bricks can.

be handled from the press to the kiln, and the timing of the variousparts are all controlled from one roller and not dependent on manuallabor for operating any part thereof.

While I have shown my device as attached to a machine for making twobricks I simultaneous, it is obvious that by a mere duplication of thevarious scoring cutters and mdulds that the device can also be appliedto presses turning out four, six, or more bricks at one operation, butregardless of the number of bricks made at one operation, only oneleverfor operating the end scoring cutters is necessary.

Having fully described my invention, what I claim is:

1. A brick surfacing machine comprising a brick press having a ram, atable se cured to said press, strips secured to said table, cutterssecured in one of said strips and extending therefrom, a movable endscoring blade adapted to be moved across the ends of a brick by thedownward movement of the ram.

2. A brick surfacingmachine comprising a brick press having a. ram, atable secured to said press, strips secured to said table, cutterslocated in some of said strips and projecting therefrom, end scoringblades slidably secured to said table, and a lever for operating saidend scoring blades across the end of a brick by the downward movement ofthe ram.

3. The brick surfacing machine of claim 1, in which the ram is providedwith rollers for operating the end scoring blades.

4. The brick surfacing machine of claim 2, in which the ram is providedwith rollers for operating the end scoring blades.

5. A brick surfacing machine comprising a brick press having a ram, atable secured to said press, guide strips located on said table topermit the passage of bricks there-between, some of said guide stripshaving scoring cutters projecting therefrom, means for feeding bricksthrough said guide strips and side scoring blades, end cutters slidablysecured to said table, a lever for operating said end scoring blades,and means carried by the ram for operat ing said lever.

6. The brick surfacing machine of claim 5, in which the ram is providedwith rollers projecting therefrom for operating said lever backward andforward during its upward and downward movement.

7. A brick surfacing machine comprising a table, guide strips secured tosaid table, cutters secured in one of said strips and projectingtherefrom, and movable end scoring blades carried by the table forscoring the ends of a brick.

In testimony whereof, I have signed my name to this specification.
